Description
Modeled after CollStream. Produces a bit stream out if an array of integers. The least significant bit comes first in each byte (LSB). Use class RedBitStream2 for most significant bit first (MSB).
Class Methods
.new
Arguments:
| collection |
An Array of integers. |
| byte |
Number of bits per byte in this collection of integers. If byte is 8 then integers should not be greater than 255. |
Instance Methods
.bytePos
Get or set the byte position.
.collection
Get the current collection.
.contents
Get the current bit stream.
.next
Step one bit forward and return the bit value at that position. Returns nil when reached the end.
.nextByte
Step forward byte number of bits. Returns an Array of bit values and can contain nil when reached the end.
.peek
Get the bit value (0/1) at the current position.
.peekByte
Get the byte at the current -bytePos position (reading from -collection).
.poke
Set the bit value (0/1) at the current position.
Arguments:
| bit |
Value 0 or 1. |
.pos
Get or set the bit position.
.put
Write a value at current position and advance the position by one bit.
Arguments:
| item |
Value 0 or 1. |
.putByte
Write a byte value at the current position and advance the position by one byte.
Arguments:
| item |
A byte value. |
.reset
Empty the -collection and set -pos to 0.
